- They are typically solid to the touch.
- A lot of lymph nodes are less than 1 centimeter in size, yet some can enlarge in response to infection or inflammation.

Now that we recognize the anatomy of lymph nodes, let’s explore where they are located in the body and also their function.
Area as well as Function of Lymph Nodes
Lymph nodes are found throughout the body, largely in collections or chains. They are tactically placed near major blood vessels as well as body organs to guarantee optimum purification of lymph liquid.

Conclusion
Lymph nodes play an important duty in our body immune system by filtering and capturing unsafe compounds in our bodies. These tiny, bean-shaped structures are spread throughout the body as well as linked by a network of vessels.
